BACKGROUND TO THE INVENTION

A number of protein kinases have already proved to be suitable target molecules for therapeutic intervention in a variety of indications, e.g. cancer and inflammatory and autoimmune diseases. Since a high percentage of the genes involved in the development of cancer which have been identified thus far encode kinases, these enzymes are attractive target molecules for the therapy of cancer in particular.

The phosphoinositide 3-kinase (PI3K) pathway is activated in a broad spectrum of human cancers. This may occur either via mutation of PI3K resulting in activation of the kinase, or indirectly via inactivation of the phosphotase and tensin homologue (PTEN) suppressor. In both cases, an activation of the signalling cascade is induced that promotes transformation of cells both in vitro and in vivo. Within the cascade, the Pi3K family of enzymes and the kinase mTOR play a pivotal role. The PI3K family comprises 15 lipid kinases with distinct substrate specificities, expression pattern and modes of regulation. They play an important role in numerous cell processes such as e.g. cell growth and differentiation processes, the control of cytoskeletal changes and the regulation of intracellular transport processes. On the basis of their in vitro specificity for certain phosphoinositide substrates the PI3-kinases can be divided into different categories. The mammalian target of rapamycin (mTOR) is a serine/threonine kinase related to the lipide kinases of the PI3-kinase family. It exists in two complexes, mTORC1 and mTORC2, which are differentially regulated, have distinct substrate specificities, and are differentially sensitive to rapamycin. The central role of mTOR in controlling key cellular growth and survival pathways has sparked interest in discovering mTOR inhibitors that bind to the ATP site and therefore target both mTORC2 and mTORC1. As a consequence, inhibition of the PI3K pathway, particularly mediated via Pi3Kα and mTOR, has emerged as an attractive target for cancer therapeutics.

5-Alkynyl-pyrimidines are described for example as protein kinases inhibiting compounds in WO2006044823.

DETAILED DESCRIPTION OF THE INVENTION

It has now surprisingly been found that compounds of general formula (1), wherein the groups R¹ to R⁴ have the meanings given below, act as inhibitors of kinases. In particular, the compounds of the invention inhibit PI3Kα and mTOR kinases. Thus, the compounds according to the invention may be used for example for the treatment of diseases connected with the activity of kinases and characterised by excessive or abnormal cell proliferation, like for example cancer.

DEFINITIONS

As used herein the following definitions apply, unless stated otherwise.

By alkyl substituents are meant in each case saturated, unsaturated, straight-chain or branched aliphatic hydrocarbon groups (alkyl group) and this includes both saturated alkyl groups and unsaturated alkenyl and alkynyl groups. Alkenyl substituents are in each case straight-chain or branched, unsaturated alkyl groups, which have at least one double bond. By alkynyl substituents are meant in each case straight-chain or branched, unsaturated alkyl groups, which have at least one triple bond.

The term heteroalkyl refers to groups which can be derived from alkyl as defined above in to its broadest sense by replacing one or more of the groups —CH₃ in the hydrocarbon chains independently of one another by the groups —OH, —SH or —NH₂, one or more of the groups —CH₂— independently of one another by the groups —O—, —S— or —NH—, one or more of the groups

by the group

one or more of the groups ═CH— by the group ═N—, one or more of the groups ═CH₂ by the group ═NH or one or more of the groups ≡CH by the group ≡N, while in all only a maximum of three heteroatoms may be present in a heteroalkyl, there must be at least one carbon atom between two oxygen and between two sulphur atoms or between one oxygen and one sulphur atom and the group as a whole must have chemical stability.

It flows from the indirect definition/derivation from alkyl that heteroalkyl is made up of the sub-groups of saturated hydrocarbon chains with hetero-atom(s), heteroalkenyl and heteroalkynyl, while further subdivision into straight-chain (unbranched) and branched may be carried out. If a heteroalkyl is supposed to be substituted, the substitution may take place independently of one another, in each case mono- or polysubstituted, at all the hydrogen-carrying oxygen, sulphur, nitrogen and/or carbon atoms. Heteroalkyl itself may be linked to the molecule as substituent both through a carbon atom and through a heteroatom.

By way of example, the following representative compounds are listed: dimethylaminomethyl; dimethylaminoethyl (1-dimethylaminoethyl; 2-dimethyl-aminoethyl); dimethylaminopropyl (1-dimethylaminopropyl, 2-dimethylaminopropyl, 3-dimethylaminopropyl); diethylaminomethyl; diethylaminoethyl (1-diethylaminoethyl, 2-diethylaminoethyl); diethylaminopropyl (1-diethylaminopropyl, 2-diethylamino-propyl, 3-diethylaminopropyl); diisopropylaminoethyl (1-diisopropylaminoethyl, 2-di-isopropylaminoethyl); bis-2-methoxyethylamino; [2-(dimethylamino-ethyl)-ethyl-amino]-methyl; 3-[2-(dimethylamino-ethyl)-ethyl-amino]-propyl; hydroxymethyl; 2-hydroxy-ethyl; 3-hydroxypropyl; methoxy; ethoxy; propoxy; methoxymethyl; 2-methoxyethyl etc.

mTOR Kinase Activity Assay

(Phosphorylation Status of mTOR Substrate 4E-BP1; TR-FRET)

mTOR assay described herein provides IC50 values indicating the activity of the compounds inhibiting mTOR activity Inhibition of mTOR is expected to be indicative of activity in treating conditions of excessive or anomalous cell proliferation such as cancer.

Assay Principle:

The mTOR kinase TR-FRET assay utilizes a physiologically relevant protein substrate for mTOR (4E-BP1, labeled with an acceptor fluorophore (Green Fluorescent Protein) and paired with a corresponding Tb-labeled phospho-specific antibody. The assay itself can be divided into two phases: the reaction phase and the detection phase.

In the reaction phase, all components required for the kinase reaction are added to the well, including the labeled protein substrate. The reaction is allowed to incubate for 60 minutes. After the reaction, EDTA is added to stop the kinase reaction, and terbium-labeled antibody is added to bind phosphorylated product. Because the terbium chelate is stable at the EDTA concentrations used to stop a kinase assay, the antibody and EDTA can be pre-mixed prior to addition to minimize pipetting steps. Binding of the terbium labeled antibody to the fluorophore-labeled phosphorylated product brings the terbium and GFP into proximity, resulting in an increase in TR-FRET. In the presence of an inhibitor, formation of phosphorylated product is reduced, and the TR-FRET value is decreased.

The mixture is then incubated for 20 minutes at room temperature. Subsequently, 20 μl of assay buffer containing 3 μM cold ATP and 0.5 μCi/20 μl 33P-ATP are added. The plates are then incubated at room temperature for 120 minutes (shaking with 300 rpm). The reaction mix is transferred onto filter plates using “filtermate harvester” from Packard: filter plates are rinsed with PBS, then the reaction mix is filtered onto the filter plate, washed 5 times with PBS and are allowed to dry for 30-60 minutes at 50° C.

The plate bottom is sealed with Perkin Elmer white adhesive foil and 25 μl/well Microscint0 are added, the top is covered with transparent adhesive foil and the plate is measured with Wallac Trilux 1450 Microbeta Counter.

As positive control serve wells containing vehicle controls (1% DMSO in assay buffer), showing non-inhibited kinase activity (high values). Wells containing assay buffer instead of enzyme can serve as control for background activity (low values).

PC3 Proliferation Test

The test is based on measurement of cellular DNA content via fluorescent dye binding. Because cellular DNA content is highly regulated, it is closely proportional to cell number. The extent of proliferation is determined by comparing cell counts for samples treated with drugs with untreated controls.

PC3 (human prostate carcinoma cell line) cells are sown in microtitre plates and incubated overnight in culture medium at 37° C. and 5% CO₂. The test substances are diluted stepwise and added to the cells such that the total volume is 200 μL/well. Cells to which diluent, but not substance, is added serve as controls. After an incubation time of 3 days, the medium is replaced by 100 μL/well dye-binding solution and the cells are incubated at 37° C. in the dark for a further 60 min. For measuring the fluorescence, excitation takes place at a wavelength of 485 nm and the emission is measured at 530 nm EC₅₀ values are calculated using the GraphPad Prism program.

AlamarBlue Assay in AN3 CA Cells

The alamarBlue cell assay provides EC₅₀ values indicative of the antiproliferative or cytotoxic effects of the compounds on the AN3 CA human endometrial cancer cell line.

1. Description

alamarBlue® is designed to provide a rapid and sensitive measure of cell proliferation and cytotoxicity in various human and animal cell lines. The assay is based on the reduction of alamarBlue in the reducing environment of living (metabolically active) cells. In the presence of added cytotoxic or antiproliferative compounds, the innate metabolic activity ceases.

AlamarBlue is soluble and stable in culture medium. Measurements are made fluorometrically by exciting at 530-560 nm and measuring emission at 590 nm. In reporting percent alamarBlue reduction by monitoring fluorescence, data are expressed as fluorescence emission intensity units as a function of time of incubation.

They can also comprise suspension aids or thickeners, such as sodium carboxymethyl cellulose, wetting agents, for example condensation products of fatty alcohols and ethylene oxide, or protectants such as p-hydroxybenzoates.

Injection and infusion solutions are produced in a customary manner, e.g. while adding isotonizing agents, preservatives, such as p-hydroxybenzoates, or stabilizers, such as alkali to metal salts of ethylenediaminetetraacetic acid, where appropriate using emulsifiers and/or dispersants, with it being possible, for example, to employ, where appropriate, organic solvents as solubilizing agents or auxiliary solvents when using water as diluent, and aliquoted into injection bottles or ampoules or infusion bottles.

The capsules, which comprise one or more active compounds or active compound combinations, can, for example, be produced by mixing the active compounds with inert carriers, such as lactose or sorbitol, and encapsulating the mixture in gelatine capsules. Suitable suppositories can be produced, for example, by mixing with excipients which are envisaged for this purpose, such as neutral fats or polyethylene glycol, or their derivatives.

Auxiliary substances which may be mentioned by way of example are water, pharmaceutically unobjectionable organic solvents, such as paraffins (e.g. petroleum fractions), oils of vegetable origin (e.g. groundnut oil or sesame oil), monofunctional or polyfunctional alcohols (e.g. EtOH or glycerol), carrier substances such as natural mineral powders (e.g. kaolins, argillaceous earths, talc and chalk), synthetic mineral powders (e.g. highly disperse silicic acid and silicates), sugars (e.g. cane sugar, lactose and grape sugar), emulsifiers (e.g. lignin, sulphite waste liquors, methyl cellulose, starch and polyvinylpyrrolidone) and glidants (e.g. magnesium stearate, talc, stearic acid and sodium lauryl sulphate).

Administration is effected in a customary manner, preferably orally or transdermally, in particular and preferably orally. In the case of oral use, the tablets can naturally also comprise, in addition to the abovementioned carrier substances, additives such as sodium citrate, calcium carbonate and dicalcium phosphate together with a variety of further substances such as starch, preferably potato starch, gelatine and the like. It is furthermore also possible to use glidants, such as magnesium stearate, sodium lauryl sulphate and talc, for the tableting. In the case of aqueous suspensions, a variety of taste improvers or dyes can also be added to the active compounds in addition to the abovementioned auxiliary substances.

For parenteral administration, it is possible to employ solutions of the active compounds to while using suitable liquid carrier materials. The dosage for intravenous administration is 1-1000 mg per hour, preferably between 5 and 500 mg per hour.

Despite this, it may be necessary, where appropriate, to diverge from the above-mentioned quantities, depending on the body weight or the nature of the route of administration, on the individual response to the medicament, on the nature of its formulation and on the time or interval at which the administration is effected. Thus, it may, in some cases, be sufficient to make do with less than the previously mentioned lowest quantity whereas, in other cases, the abovementioned upper limit has to be exceeded. When relatively large quantities are being administered, it may be advisable to divide these into several single doses which are given over the course of the day.

The following formulation examples illustrate the present invention without, however, restricting its scope:
